GHSA-V7PC-74H8-XQ2H Hickory DNS failure to verify self-signed RRSIG for DNSKEYs

Summary The DNSSEC validation routines treat entire RRsets of DNSKEY records as trusted once they have established trust in only one of the DNSKEYs. As a result, if a zone includes a DNSKEY with a public key that matches a configured trust anchor, all keys in that zone will be trusted to...
